Step-by-step explanation:
(A)The given equations are:
and
Taking the ordered pair (3,0),
and
which is satisfied. Thus, option A (3,0) is correct.
(B) The two equations are:
and
Adding both the equations, we get
Therefore, substituting the value of x in any of the two given equations,
Hence, x=3 and y=6
(C) Let "b" represents Becky's score and "C" be Cathy's score.
Then, According to the question, we get
and
Thus, Option B is correct.
(D) The given equations are:
and
Now, substituting the value of x=y+5 in the equation, we get
Thus, option C is correct.
Answer: It is mutually exclusive and exhaustive.
Step-by-step explanation:
Since we have given that
Owns apple No apple Total
With kids 500.2 319.8 820
Without kids 182.4 197.6 380
Total 682.6 517.4 1200
P(Households without kids) =
P(Households with kids) =
And P(A∪B) = 0.316+0.683 = 0.999 ≈ 1
Since the two event are disjoint so, the probability of both occurring is 0 and the probability of either occurring is the sum of each occurring.
Hence, it is mutually exclusive and exhaustive.
